to a process for the preparation of those compounds and tautomers, to the use of those compounds and tautomers, to pesticidal compositions the active ingredient of which is selected from those compounds and tautomers, or the agrochemically acceptable salts thereof, and to a process for the preparation of those compositions and to the use of those compositions.

Some of the compounds of formula I may be in the form of tautomers. When, for example, R₃ is hydrogen and X is N, corresponding compounds of formula I, that is to say, those having a --N(H)--C(R₄)═N--R₅ partial structure, may be in equilibrium with the relevant tautomers which have a --N═C(R₄)--N(H)--R₅ partial structure. Hereinafter, therefore, the compounds of formula I are, where appropriate, also to be understood as being corresponding tautomers, even when the latter are not mentioned specifically in every case.

The compounds of formula I and, where appropriate, their tautomers may be in the form of salts. Compounds of formula I that have at least one basic centre can, for example, form acid addition salts. These are formed, for example, with strong inorganic acids, such as mineral acids, for example sulfuric acid, a phosphoric acid or a hydrohalic acid, with strong organic carboxylic acids, such as unsubstituted or substituted, for example halo-substituted, C₁ -C₄ alkanecarboxylic acids, for example acetic acid, saturated or unsaturated dicarboxylic acids, for example oxalic, malonic, maleic, fumaric or phthalic acid, hydroxycarboxylic acids, for example ascorbic, lactic, malic, tartaric or citric acid, or benzoic acid, or with organic sulfonic acids, such as unsubstituted or substituted, for example halo-substituted, C₁ -C₄ alkane- or aryl-sulfonic acids, for example methane- or p-toluene-sulfonic acid. In addition, compounds of formula I having at least one acidic group can form salts with bases. Suitable salts with bases are, for example, metal salts, such as alkali metal or alkaline earth metal salts, for example sodium, potassium or magnesium salts, or salts with ammonia or an organic amine, such as morpholine, piperidine, pyrrolidine, a mono-, di- or tri-lower alkylamine, for example ethyl-, diethyl-, triethyl- or dimethyl-propyl-amine, or a mono-, di- or tri-hydroxy-lower alkylamine, for example mono-, di- or tri-ethanolamine. Furthermore, corresponding internal salts may possibly be formed. Within the scope of the invention agrochemically advantageous salts are preferred; however, salts that have disadvantages with respect to agrochemical uses but which can be used, for example, for the isolation or purification of free compounds of formula I or the agrochemically acceptable salts thereof are also included. Hereinbefore and hereinafter, therefore, the expression "compound of formula I" also includes the salts of those compounds, the tautomers of those compounds and the salts of the tautomers.

The compounds of formula II and the compounds of formula III and, where appropriate, the tautomers thereof and also the salts of the compounds and tautomers are known or can be prepared analogously to known compounds.

Variant b:

Suitable acids for facilitating HL-removal are, for example, those indicated above as being suitable for the formation of acid addition salts with compounds of formula I.

Suitable bases for facilitating HL-removal are, for example, alkali metal or alkaline earth metal hydroxides, hydrides, amides, alkanolates, carbonates, dialkylamides or alkylsilylamides; alkylamines, alkylenediamines, unsubstituted or N-alkylated, unsaturated or saturated cycloalkylamines, basic heterocycles, ammonium hydroxides and carbocyclic amines. There may be mentioned by way of example: sodium hydroxide, hydride, amide, methanolate and carbonate, potassium tert-butanolate and carbonate, lithium diisopropylamide, potassium bis(trimethylsilyl)amide, calcium hydride, triethylamine, triethylenediamine, cyclohexylamine, N-cyclohexyl-N,N-dimethylamine, N,N-diethylaniline, pyridine, 4-(N,N-dimethylamino)pyridine, N-methylmorpholine, benzyltrimethylammonium hydroxide and also 1,5-diazabicyclo[5.4.0]undec-5-ene (DBU).

The reactants can be reacted with one another as such, that is to say without the addition of a solvent or diluent, for example in the melt. Generally, however, the addition of an inert solvent or diluent or a mixture thereof is advantageous. There may be mentioned as examples of such solvents and diluents: aromatic, aliphatic and alicyclic hydrocarbons and halogenated hydrocarbons, such as benzene, toluene, xylene, chlorobenzene, bromobenzene, petroleum ether, hexane, cyclohexane, dichloromethane, trichloromethane, dichloroethane or trichloroethane; esters, such as ethyl acetate; ethers, such as diethyl ether, tert-butyl methyl ether, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol dimethyl ether, tetrahydrofuran or dioxane; ketones, such as acetone, methyl ethyl ketone or methyl isobutyl ketone; alcohols, such as methanol, ethanol, propanol, butanol, ethylene glycol or glycerol; amides, such as N,N-dimethylformamide, N,N-dimethylacetamide, N-methylpyrrolidone or hexamethylphosphoric acid triamide; nitriles, such as acetonitrile; and sulfoxides, such as dimethyl sulfoxide. If the reaction is carried out in the presence of an acid, it is possible for acids used in excess, for example strong organic carboxylic acids, such as unsubstituted or substituted, for example halo-substituted, C₁ -C₄ alkanecarboxylic acids, for example formic acid, acetic acid or propionic acid, to serve also as solvent or diluent. If the reaction is carried out in the presence of a base it is possible for bases used in excess, such as triethylamine, pyridine, N-methylmorpholine or N,N-diethylaniline, to serve also as solvent or diluent.

The reaction is advantageously carried out in a temperature range of from approximately -20° C. to approximately +180° C., preferably from approximately 0° C. to approximately +120° C., in many cases at the reflux temperature of the solvent used.

In a preferred form of variant b), a compound (IV) is reacted at reflux temperature in an ether, preferably in dioxane, and in the presence of an alkylamine, preferably in the presence of triethylamine, with a compound (V) wherein L is alkoxy.

In a further preferred form of variant b), a compound (IV) is reacted at reflux temperature in an aromatic hydrocarbon, preferably in toluene, and in the presence of an organic carboxylic acid, preferably in the presence of acetic acid, with a compound (V) wherein L is hydroxy, or with a tautomer thereof.

The compounds of formula IV and the salts thereof, and also the compounds of formula V and, where appropriate, the tautomers thereof, in each case in free form or in salt form, are known or can be prepared analogously to known compounds.

A compound I obtainable in accordance with the process or in another manner or, where appropriate, a tautomer thereof can be converted in a manner known per se into a different compound I by replacing one or more substituents of the starting compound I in customary manner by (an)other substituent(s) according to the invention.

For example:

hydroxy groups R₁ and/or R₂ can be alkylated to C₁ -C₄ alkoxy groups R₁ and/or R₂ ;

halogen R₁ and/or R₂ can be introduced into unsubstituted positions of the phenyl ring(s) concerned; or

mercapto groups R₅ can be oxidised to sulfinyl or sulfonyl groups R₅, or sulfinyl groups R₅ can be oxidised to sulfonyl groups R₅.

In that conversion it is possible, depending on the chosen starting materials and reaction conditions suitable for the particular purpose, to replace, in one reaction step, only one substituent by another substituent according to the invention, or it is possible in the same reaction step to replace several substituents by other substituents according to the invention.

Salts of compounds of formula I can be prepared in a manner known per se. For example, acid addition salts of compounds of formula I are obtained by treatment with a suitable acid or with a suitable ion-exchange reagent, and salts with bases can be obtained by treatment with a suitable base or a suitable ion-exchange reagent.

Salts of compounds of formula I can be converted in customary manner into the free compounds of formula I; for example, acid addition salts can be converted by treatment with a suitable basic agent or a suitable ion-exchange reagent, and salts with bases, for example, by treatment with a suitable acid or a suitable ion-exchange reagent.

Salts of compounds of formula I can be converted in a manner known per se into other salts of compounds of formula I; for example, acid addition salts can be converted into other acid addition salts, for example by treating a salt of an inorganic acid, such as a hydrochloride, with a suitable metal salt, such as a sodium, barium or silver salt, of an acid, for example with silver acetate, in a suitable solvent in which an inorganic salt being formed, for example silver chloride, is insoluble and is thus eliminated from the reaction mixture.

Depending on the procedure and reaction conditions, the compounds of formula I having salt-forming properties can be obtained in free form or in the form of salts.

The compounds of formula I and, where appropriate, the tautomers thereof, in each case in free form or in salt form, may be in the form of one of the possible isomers or in the form of a mixture thereof; for example, depending on the number and absolute and relative configuration of asymmetric carbon atoms occurring in the molecule and/or depending on the configuration of non-aromatic double bonds occurring in the molecule, they may be in the form of pure isomers, such as antipodes and/or diastereoisomers, or in the form of mixtures of isomers, such as mixtures of enantiomers, for example racemates, mixtures of diastereoisomers or mixtures of racemates; the invention relates both to the pure isomers and to all possible mixtures of isomers and is to be understood accordingly hereinbefore and hereinafter, even when stereochemical details are not specifically mentioned in every case.

Mixtures of diastereoisomers and mixtures of racemates, obtainable in accordance with the process--depending on the starting materials and procedures chosen--or obtainable in another manner, of compounds of formula I and, where appropriate, of the tautomers thereof, in each case in free form or in salt form, can be separated into the pure diastereoisomers or racemates on the basis of the physico-chemical differences between the constituents in known manner, for example by fractional crystallisation, distillation and/or chromatography.

Correspondingly obtainable mixtures of enantiomers, such as racemates, can be resolved into the optical antipodes in accordance with known methods, for example by recrystallisation from an optically active solvent, by chromatography on chiral adsorbents, for example high pressure liquid chromatography (HPLC) on acetylcellulose, using suitable micro-organisms, by cleavage with specific immobilised enzymes, by means of the formation of inclusion compounds, for example using chiral crown ethers, only one enantiomer being complexed, or by conversion into diastereoisomeric salts, for example by reaction of a basic end product race mate with an optically active acid, such as a carboxylic acid, for example camphoric, tartaric or malic acid, or a sulfonic acid, for example camphorsulfonic acid, and separation of the mixture of diastereoisomers so obtained, for example on the basis of their different solubilities by fractional crystallisation, into the diastereoisomers from which the desired enantiomer can be freed by the action of suitable, for example basic, agents.

Apart from by separating corresponding mixtures of isomers, pure diastereoisomers and enantiomers can also be obtained according to the invention by generally known methods of diastereoselective and enantioselective synthesis, respectively, for example by carrying out the process according to the invention with educts having correspondingly suitable stereochemistry.

Advantageously, the biologically more active isomer, for example enantiomer or diastereoisomer, or mixture of isomers, for example a mixture of enantiomers or a mixture of diastereoisomers, is isolated or synthesised, if the individual components have different biological activities.

The compounds of formula I and, where appropriate, the tautomers thereof, in each case in free form or in salt form, can also be obtained in the form of their hydrates and/or may include other solvents, for example solvents that are used, where appropriate, for the crystallisation of compounds that are in solid form.

The invention relates to all those forms of the process according to which a compound obtainable as starting material or intermediate at any stage of the process is used as starting material and all or some of the remaining steps are carried out or a starting material is used in the form of a derivative or salt and/or its racemates or antipodes or, especially, is formed under the reaction conditions.

In the process of the present invention, it is preferable to use those starting materials and intermediates or the salts thereof that result in the compounds of formula I or the salts thereof described in the introduction as being especially valuable.

The invention relates especially to the preparation processes described in Examples 1 to P3.

The invention relates also to those starting materials and intermediates or the salts thereof that are novel and which are used according to the invention for the preparation of the compounds of formula I or the salts thereof, to their use and to processes for the preparation thereof.

The good pesticidal activity of the compounds according to the invention corresponds to a mortality of at least 50 to 60% of the mentioned pests.

The activity of the compounds according to the invention and of the compositions that comprise those compounds can be substantially broadened and adapted to prevailing circumstances by the addition of other insecticides. Suitable additives are, for example, representatives of the following classes of active substance: organophosphorus compounds, nitrophenols and derivatives thereof, formamidines, ureas, carbamates, pyrethroids, chlorinated hydrocarbons and Bacillus thuringiensis preparations.

The compounds according to the invention are used in unmodified form or, preferably, together with the adjuvants conventionally employed in formulation technology, and can therefore be processed in known manner e.g. into emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts and granules, and also encapsulations in polymer substances. As with the compositions, the methods of application, such as spraying, atomising, dusting, scattering or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances.

The formulations, i.e. the compositions, preparations or mixtures comprising the compound (active ingredient) according to the invention, or a combination of that compound with other insecticides, and, where appropriate, solid or liquid adjuvants, are prepared in known manner, e.g. by homogeneously mixing and/or grinding the active ingredient with the adjuvants, such as extenders, e.g. solvents or solid carriers, or such as surface-active compounds (surfactants).

Suitable solvents are: aromatic hydrocarbons, preferably the fractions containing 8 to 12 carbon atoms of alkylbenzenes, such as xylene mixtures or alkylated naphthalenes, aliphatic or cycloaliphatic hydrocarbons, such as cyclohexane, paraffins or tetrahydronaphthalene, alcohols, such as ethanol, propanol or butanol, glycols and their ethers and esters, such as propylene glycol, dipropylene glycol ether, ethylene glycol, ethylene glycol monomethyl or monoethyl ether, ketones, such as cyclohexanone, isophorone or diacetone alcohol, strongly polar solvents such as N-methyl-2-pyrrolidone, dimethyl sulfoxide or N,N-dimethylformamide, water and vegetable oils or epoxidised vegetable oils, such as rape, castor, coconut or soybean oil or epoxidised rape, castor, coconut or soybean oil; and, where appropriate, also silicone oils.

The solid carriers used, e.g. for dusts and dispersible powders, are normally natural mineral fillers such as calcite, talcum, kaolin, montmorillonite or attapulgite. In order to improve the physical properties it is also possible to add highly dispersed silicic acids or highly dispersed absorbent polymers. Suitable granulated adsorptive carriers are porous types, for example pumice, broken brick, sepiolite or bentonite; and suitable nonsorbent carriers are calcite or sand. In addition, a great number of granulated materials of inorganic or organic nature can be used, especially dolomite or pulverised plant residues.

Depending on the nature of the compound according to the invention to be formulated or the combination of that compound with other insecticides, suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants having good emulsifying, dispersing and wetting properties. The term "surfactants" will also be understood as comprising mixtures of surfactants.

Non-ionic surfactants are preferably polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols, said derivatives containing 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon moiety and 6 to 18 carbon atoms in the alkyl moiety of the alkylphenols. Further suitable non-ionic suffactants am the water-soluble adducts of polyethylene oxide with polypropylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol containing 1 to 10 carbon atoms in the alkyl chain, which adducts contain 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups. These compounds usually contain 1 to 5 ethylene glycol units per propylene glycol unit. Representative examples of non-ionic surfactants are nonylphenolpolyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol. Fatty acid esters of polyoxyethylene sorbitan, e.g. polyoxyethylene sorbitan trioleate, are also suitable non-ionic suffactants.

Cationic surfactants are preferably quaternary ammonium salts which contain, as N-substituent, at least one C₈ -C₂₂ alkyl radical and, as further substituents, unsubstituted or halogenated lower alkyl, benzyl or hydroxy-lower alkyl radicals. The salts are preferably in the form of halides, methyl sulfates or ethyl sulfates, e.g. stearyltrimethylammonium chloride or benzyldi(2-chloroethyl)ethylammonium bromide.

Both so-called water-soluble soaps and water-soluble synthetic surface-active compounds are suitable anionic surfactants. Suitable soaps are the alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts of higher fatty acids (C₁₀ -C₂₂), e.g. the sodium or potassium salts of oleic or stearic acid, or of natural fatty acid mixtures which can be obtained e.g. from coconut oil or tall oil; fatty acid methyltaurin salts may also be mentioned as surfactants. More frequently, however, so-called synthetic surfactants are used, especially fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates. The fatty sulfonates or sulfates are usually in the form of alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts and generally contain a C₈ -C₂₂ alkyl radical, which also includes the alkyl moiety of acyl radicals, e.g. the sodium or calcium salt of lignosulfonic acid, of dodecyl sulfate or of a mixture of fatty alcohol sulfates obtained from natural fatty acids. These compounds also comprise the salts of sulfated and sulfonated fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfonic acid groups and one fatty acid radical containing approximately 8 to 22 carbon atoms. Examples of alkylarylsulfonates are the sodium, calcium or triethanolammonium salts of dodecylbenzenesulfonic acid, dibutylnaphthalenesulfonic acid, or of a condensate of naphthalenesulfonic acid and formaldehyde. Also suitable are corresponding phosphates, e.g. salts of the phosphoric acid ester of an adduct of p-nonylphenol with 4 to 14 tool of ethylene oxide, or phospholipids.

The surfactants indicated above are to be regarded only as examples; the relevant literature describes many other surfactants that are customarily employed in formulation technology and are suitable according to the invention.

The pesticidal compositions generally comprise 0.1 to 99%, especially 0.1 to 95%, of a compound according to the invention or a combination of that compound with other insecticides, and 1 to 99.9%, especially 5 to 99.9%, of a solid or liquid adjuvant, it being possible for 0 to 25%, especially 0.1 to 20%, of the composition to consist of a surfactant (% denotes percentage by weight in each case). Whereas commercial products will preferably be formulated as concentrates, the end user will normally employ dilute formulations, which comprise substantially lower concentrations of active ingredient. Typical application concentrations are 0.1 to 1000 ppm, preferably 0.1 to 500 ppm of active ingredient. The rates of application per hectare are generally 1 to 1000 g of active ingredient per hectare, preferably 25 to 500 g/ha.

Preferred formulations are composed especially of the following constituents (throughout, percentages are by weight):

Emulsifiable concentrates:

active ingredient: 1 to 90%, preferably 5 to 20%

surfactant: 1 to 30%, preferably 10 to 20%

liquid carrier: 5 to 94%, preferably 70 to 85%

active ingredient: 0.1 to 10%, preferably 0.1 to 1%

solid carrier: 99.9 to 9O%, preferably 99.9 to 99%

active ingredient: 5 to 75%, preferably 10 to 50%

water: 94 to 24%, preferably 88 to 30%

surfactant: 1 to 40%, preferably 2 to 30%

active ingredient: 0.5 to 90%, preferably 1 to 80%

surfactant: 0.5 to 20%, preferably 1 to 15%

Granules:

active ingredient: 0.5 to 30%, preferably 3 to 15%

solid carrier: 99.5 to 70%, preferably 97 to 85%

The compositions may also comprise further adjuvants such as stabilisers, for example vegetable oils or epoxidised vegetable oils (for example epoxidised coconut oil, rape oil or soybean oil), antifoams, for example silicone oil, preservatives, viscosity regulators, binders and/or tackifiers, as well as fertilisers or other active ingredients for obtaining special effects.

The following Examples serve to illustrate the invention. They do not limit the invention. Temperatures are given in degrees Celsius.
